    Default Spanner and Safe Mode.

    I have a quick question, when I am on say the A1 for example and driving at a constant speed of around 70mph after about 5 miles or so the spanner light comes on and goes into Safe Mode briefly for around 30 seconds then off again, it will keep doing this for a few times, which is annoying as it keeps turning off the cruise control.

    This does not happen when I am driving home from work, there is a stretch of road which I drive constant at 70mph but as I am speeding up and slowing down and using gears it doesn't seem to go into safe mode.

    Things I have done, checked all pipes all are fine, cleaned the EGR valve and inlet manifold as the safe mode used to happen after car warmed up, it is so intermittant its unbelievable, only time its consistant is when driving on motorway or dual carraigways. please note it is not only when using cruise control this is just something I added as I would like to use it lol..


    Car I have is a 2.0 DTi any ideas?

    Cheers in advance.

    I had a 2.0 dti vectra B. When I drove down the A4174 ringroad evertime I went over the valley with the river underneath the eml light came on and then went out at the same place everytime. Also with a 2.2dti omega driving over the M5 m4 interchange every time eml light in same place and then goes out. Strange could never solve.

    Unusual that it goes into safe mode briefly
    Normally once safe mode is activated it stays on

    As you are driving with the cruise on and it occurs, but not when you are driving with the cruise off, this should give a hint as to where the fault is and that it is an electrical module fault

    Next time it occurs leave the engine running and get the live fault code read
    As you have a 2003MY, try the pedal test as that should work

    have you tried cleaning the inlet manifold . my 2.0 dti use to do it and i cleaned just the egr and boost and maf sensors . but after just 3 weeks it kept coming back . so someone said clean the inlet manifold . it cost around £20 for the gaskets and about 2 hours ish . there is a how 2 on here for cleaning a 2.2 dti inlet but it is the same .
